The invention discloses an optimal design method of a rubber suspension and the rubber suspension, and belongs to the technical field of rubber suspensions. The design method comprises the following steps: constructing a response surface model for the rigidity Kv and fatigue life Nf of the rubber mount, calculating polynomial coefficients beta0 and betai by using SPSSAU data analysis software, judging an abnormal value, and detecting whether sample data is available or not; the response surface model is subjected to precision analysis through Latin hypercube sampling, a Kv response curve and an Nf response curve are obtained, the fitting precision of the Kv response curve is not lower than 0.9959, and the fitting precision of the Nf response curve is not lower than 0.9669; matlab software is used, a gametiobj function is used for multi-objective optimization, a plurality of groups of multi-objective optimization non-inferior solution sets are obtained, and simulation verification of an optimization result is carried out. According to the optimization design method, the parameters of the preliminarily designed rubber mount can be optimized, so that the optimized rubber mount is designed, and the performance of the rubber mount meets the use requirements.

    本发明公开了一种橡胶悬置的优化设计方法及橡胶悬置,属于橡胶悬置技术领域。该设计方法包括步骤:对橡胶悬置刚度Kv与疲劳寿命Nf构建响应面模型,利用SPSSAU数据分析软件计算出多项式系数β0、βi,对异常值进行判断,检测样本数据是否可用;通过拉丁超立方抽样对响应面模型进行精度分析,得到Kv响应曲线和Nf响应曲线,Kv响应曲线的拟合精度不低于0.9959、Nf响应曲线的拟合精度不低于0.9669;使用Matlab软件,使用“gamultiobj”函数进行多目标优化,得到若干组多目标优化非劣解集,进行仿真验证优化结果。本发明的优化设计方法能够将初步设计的橡胶悬置的参数进行优化,从而设计得到最优化的橡胶悬置,使其性能满足使用的要求。
